Goodman 10728343 Limit Switch

The Goodman 10728343 is a genuine OEM temperature limit switch for the WGGE4336A045MAB gas furnace and compatible Goodman/Amana models. This snap-disc control monitors heat-exchanger or plenum temperature and opens the circuit when it climbs above the factory setpoint, shutting down the burner to prevent overheating. It automatically resets once temperatures return to a safe range, making it a first-line thermal safety for normal furnace cycling.

Specifications

Type: Auto-reset snap-disc limit switch
Contact configuration: Normally closed (opens on temperature rise)
Function: Overheat protection / burner cutout
Fit: Goodman WGGE4336A045MAB and compatible furnaces
OEM Part Number: 10728343

OEM vs. Generic

The OEM 10728343 is calibrated to the trip and reset temperatures Goodman specifies for this furnace. Generic snap discs are often stocked in a few generic setpoints that may not exactly match, causing premature cycling or delayed protection. Choosing OEM preserves proper furnace behavior and warranty coverage.

Installation Difficulty

Easy (2/5). Typically two mounting screws and two spade terminals. Cut power to the furnace first. If the limit was tripping, correct any airflow restriction before returning the unit to service.
